Phylogenetic representation of wheat evolution. Wheat evolution is shown starting ∼7 MYA from a progenitor that gave rise to the (A), (B), and (D) lineages that merged to form bread wheat. The relative timing of the major speciation events is shown in the horizontal axis and described in the boxes above. The tree is adapted from Glémin et al. (2019); Li et al. (2022); Avni et al. (2021). The diploid species related to the D genome (asterisks) are Aegilops bicornis, Ae. longissima, Ae. searsii, Ae. sharonensis, Ae. caudata, Ae. comosa, Ae. umbellulata, and Ae. uniaristata.
